JULIUS .I. DRAWE, OF NEW ORLEANS, LOUISIANA.

LIQUID-SAMPLER.

To all whom it may concern:

Be it known that I, JULIUS J. DRAWE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and .useful Improvements in Liquid -Samplers;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

This invention relates to improvements in sampling tubes, and it is especially adapted for use as a liquid sampler, and more particularly designed as a sampler for oils.

The primary object of the invention is to secure a cheap and efficient device which will accurately sample the contents of the tank or other receptacle for the full depth of same.

It might be advantageous to make the tube out of glass or other transparent material, and I do not restrict myself to any particular form of material or metal.

Broadly speaking, the invention consists of a tube provided with an enlarged chamber at the base thereof having an opening at the bottom, which opening is controlled by a gate mounted within said chamber and operated by reciprocating means extending longitudinally through said tube.

While I do not limit myself to the exact details shown and described, still for the purpose of disclosure reference is had to the accompanying drawings illustrating a practical embodiment of the invention, in which like letters designate the same parts in the several views, and in which- Figure 1 is a longitudinal sectional view through the tube and base chamber and the hollow gates thereof, showing said gates in their open osition, the tube and operating rod being s own broken away. Fig. 2 is a similar view showing the gates closed, and Fig. 3 is a fragmentary view in elevation, on a smaller scale showing the top of the sampler tube with a lever for operating the reciprocating rod and means for locking said lever.

1 designates the sampler tube, which is provided at its base with an enlarged chamber. In the drawings, this enlarged chamber is shown as comprising a spherical chamber formed by a plurality of detachablyconnected eomplemental members, one of which, designated at 2, is shown as being detachably connected to the sampler tube, and

another of which, designated at 8, being detachably connected to the first mentioned member, and being provided at its bottom with an opening 4. Snugly fitting within said chamber and cooperating to control said opening 4 are a pair of spherical sector shaped hollow gates 5 and 6, one of said gates, as 5, being provided with ears 7 coop crating with pintles 8 carried by the other gate, whereby said gates are centrally connected together. The gates themselves comprise the thickened base or bearing members 9 and 10, provided centrally at their upper ends with inwardlyextending lugs 11. and. 12. The walls of said gates 5 and 6 are preferably of less thickness than said base or bearing portion, and terminate at one end in adjacent cooperating semi-circular flaring lips 13 and 14. 15 designates a pair of links pivotally connected at one end to the respective lugs 11 and 12, and at their upper ends pivotally connected to reciprocating means, such as a rod 16 extending longitudinally through said sampler tube 1.

At the upper end of the sampler tube, the same is provided with a cap piece 17 having a Vertical arm 18 and a longer slotted vertical arm 19. A lever 20 is pivotally connected as at 21 to the rod 16, and is also pivotally secured, as at 22, to the short arm 18, the free end of the lever operating within said slotted vertical arm 19, and being provided with a handle portion 23.

Any suitable means may be employed for locking the lever in its lowermost position, as shown in Fig. 3, and in the drawings this has simply been shown conventionally by a locking button or short lever 24, which may be swung around on its pivot to allow the lever 20 to move upwardly within the slot of the upright guide 19, but which will in the position shown in Fig. 3 engage said lever and hold it down.

From the foregoing description, the operation of the device will be apparent, but may be briefly referred to as follows:The sampler tube with the gates open, as shown in Fig. 1, is let down into the oil or other liquid in the tank or other receptacle, and when it has reached the bottom, or when it is at the desired level of the oil to be sampled, the lever 20 is thrown downwardly, forcing the rod 16 downwardly also, together with the links 15, which in turn simultaneously force the spherical sector shaped gates around the walls of the spherical chamber, the bearing bases 9 and 10 acting as bearing plates, and the pivotal connections 7 and 8 assisting in keeping the gates in position. When the down stroke has been completed the flaring I lips 13 and 14 will snugly fit when the lever may be locked by the button 24 and the parts held in this position. The tube may then be Withdrawn and the samples tested.

It will be observed that in mounting the gates, there is no pivotal connection between the gates and the walls of the spherical chamber, and it will also be observed that by the construction illustrated the members composing the spherical chamber and the opfirating parts may be readily detached at wi Having thus described the invention, what I claim is 1. The combination of a sampler tube provided at its lower end with an enlarged circular base chamber having an opening at the bottom thereof, a curved gate within said chamber and concentric therewith for closing nected with said gate, substantially as de-.

scribed.

3. The combination of a sampler tube pro vided at its lower end with a hollow member of spherical contour, a complemental hollow member of spherical contour detachably secured to said first member and provided with a base opening, said members forming a spherical chamber, a hollow spherical sector gate mounted within said chamber and concentric therewith and cooperating to control said base opening, and reciprocating means extending through said tube and connected with said gate, substantially as described.

4. The combination of .a sampler tube, a hollow spherical member detachably secured to said sampler tube at its lower end, and said spherical member being formed from a pair of detachably-connected complemental members, the bottom member being provided with a base opening, a spherical sector gate mounted within said spherical member and concentric therewith, and reciprocating means extending through said tube connected at one end to said gate, substantially as described.

5. The combination of a sampler tube provided at one end with an enlarged base chamber having an opening in the bottom thereof, a pair of oppositely disposed gates simultaneously cooperating to control said opening, reciprocating means extending through said sampler tube, and link connections between said reciprocating means and said pair of gates, substantially as described.

6. The combination of a sampler tube provided at its lower end with an enlarged circular chamber provided with an opening at its lower end and a pair of curved gates in said chamber and concentric therewith, said gates simultaneously cooperating to control said opening, reciprocating means extending through said tube, and link connections between said reciprocating means and said gates, substantially as described.

7. The combination of a sampler tube pro vided at its lower end with a spherical base chamber having an opening at the bottom thereof, a pair of pivoted spherical sector shaped gates within said chamber simult'aneously cooperating to close said opening, reciprocating means extending through said tube, and link connections between said reciprocating means and said gates, substantially as described.

8. The combination of a sampler tube pro vided at its base with an enlarged spherical chamber having an o ening in the bottom thereof, a pair of splierical sector shaped gates centrally pivoted within said chamber, said gates comprising a thickened base bearing provided with inwardly-extending lugs at oneend, the spherical walls of said gates being thinner than said base portion and terminating in semicircular flaring lips, a reciprocating rod extending through said sampler tube, and links connecting the lower end of said rod with said lugs, substantially as described.

9. The combination of a sampler tube pro vided with an enlarged base chamber having an opening in the bottom thereof, a gate within said chamber for controlling said opening, a reciprocating rod extending through said tube and connected to said gate, a lever mounted on said tube and connected to said reciprocating rod, and means for locking said lever at the end of said rods downward stroke comprising a slotted extension on said tube receiving the free end of said lever and amember pivoted on said extension adjacent its slot, substantially as described.

In testimony whereof, I affix my signature, in presence of two witnesses.
